If you buy the desk anglepoise, you can get a bracket which lets you attach it to the wall - it costs about the same but means you can use it either/or. You can't do it the other way round.
is this specific to the Herbert Terry? just switching the crappy flexy plastic clamp on the Tertial for a proper steel G-clamp has made a world of difference, but I need more lamps too.
